The purpose of this study is to propose measures to increase evacuation safety by calculating the habitable time using a fire and evacuation simulation program for the Room-escape cafe currently in operation, and comparing and analyzing it with the evacuation required time. Assuming a fire due to overheating of electric heaters in use in front of the warehouse, the habitable time was calculated through fire simulation, and the occupant's evacuation time calculated through evacuation simulation according installation of safety facilities, etc. was compared and analyzed with the habitable time. In the case of escape room cafes with safety facilities installed, evacuation safety was satisfied, but in escape room cafes without safety facilities, the evacuation safety was not secure. As a result of analyzing evacuation safety for each scenario based on the ASET analyzed in the fire simulation, it was found that in scenario 1, evacuation safety was secured and everyone successfully evacuated, while in scenario 2, no one succeeded in evacuation. These results can be said to confirm that the installation of safety facilities is very important in business establishments such as escape room cafes, which become enclosed structures when games are started.

In this study, for the purpose of reducing the catch of small giant octopus in a net pot, an escape experiment of octopus was performed on five types of escape rings of different sizes. As a result of the experiment, the smallest giant octopus with a weight of 406 g was found to escape from an escape ring with a diameter of 30 mm or larger, and 592 g octopus, a weight similar to the octopus of the current minimum landing weight (600 g), escaped from an escape ring with a diameter of larger than 40 mm. An individual weight with 406 g becomes 39 mm when converted from a diameter of 25 mm circular escape vent; that is, the circumference to the inner diameter of the mesh. It can be inferred that the converted mesh size of 39 mm cannot escape. Logistic regression analysis was performed using a generalized linear model (GLM) to investigate the correlation between the ratio of escape ring size/Mantle diameter (R/MD) and the escape rate. As a result, it was found that there was a significant correlation between the R/MD ratio and the escape rate and that the higher the R/MD ratio, the greater the escape rate. As a result of logistic regression analysis, the R/MD value was denoted 0.520 with the 50% escape rate. In addition, it can be estimated to be about 50 mm when converted to the mesh size. Therefore, in this study, the diameter of the escape ring and the size of the escape possible of the octopus were experimentally considered. It was found that there was a significant correlation.

This study aims to understand the opening efficiency of the finless porpoise escape guide net by the type of extension net that is the part to which the escape guide net is attached in stow net. To this end, extension nets were manufactured in full size and the net mouth area and towing tension were investigated according to the towing speed (0.2, 0.4, 0.6 and 0.8 m/s) and the type of extension net (25 mm net and raschel net) in the water tank. As a result, the net mouth area of the guide net was larger when the raschel net was used for the extension net than when the 25 mm net was used under all towing speeds. In addition, regardless of the type of extension net, the net mouth area reached about 80% of the maximum value at a towing speed of 0.4 m/s. In the field, fishing operation of stow net is performed only when the current speed is above 0.4 m/s. Therefore, the speed of 0.4 m/s was confirmed as a meaningful value to determine whether it is possible to operate. As a result of analyzing the relationship between the net mouth area of the guide net and the towing tension, it was confirmed that the difference in the net mouth area of the guide net according to the type of the extension net was due to the difference in the solidity ratio.

We investigate the escape of Lyβ from emission nebulae with a significant population of excited hydrogen atoms in the level n = 2, rendering them optically thick in Hα. The transfer of Lyβ line photons in these optically thick regions is complicated by the presence of another scattering channel leading to re-emission of Hα, alternating their identities between Lyβ and Hα. In this work, we develop a Monte Carlo code to simulate the transfer of Lyβ line photons incorporating the scattering channel into Hα. Both Hα and Lyβ lines are formed through diffusion in frequency space, where a line photon enters the wing regime after a fairly large number of resonance scatterings with hydrogen atoms. Various line profiles of Hα and Lyβ emergent from our model nebulae are presented. It is argued that the electron temperature is a critical parameter which controls the flux ratio of emergent Lyβ and Hα. Specifically for T = 3 × 104 K and Hα line center optical depth α = 10, the number flux ratio of emergent Lyβ and Hα is ∼ 49 percent, which is quite significant. We propose that the leaking Lyβ can be an interesting source for the formation of Hα wings observed in many symbiotic stars and active galactic nuclei. Similar broad Hα wings are also expected in Lyα emitting halos found in the early universe, which can be potentially probed by the James Webb Telescope in the future.

The purpose of this study is to classify the types of Room-Escape games based on play and to derive unique narrative conventions of Room-Escape games that appear on various platforms such as online, offline, and virtual reality. The Room-Escape game sets up the 'room' and strengthens the magic circle, allowing the player to experience the 'insideness' of the place. It also applies the plot of 'the riddle' to induces players to solve puzzles and quests, as well as to infer narrative satellite events and probabilities. The Room-Escape game is a unique game genre that appears through the integration of game and narrative. It is classified into Escape-purpose-oriented type that emphasizes interaction with objects and rules, and Escape-process-oriented type which shows the enhancement of narrative features. The Room-Escape game is a game that reflects a contemporary aspect of Korean modern society desiring to escape from daily life and return at the same time.

솔수염하늘소는 소나무에 시들음 증상을 유발하여 괴사시키는 소나무재선충을 매개하는 대표적 매개충이다. 소나무재선충병 고사목 방제 살충처리 방법으로 훈증방법을 대체할 수 있는 그물망을 이용한 방제법이 도입되고 있다. 본 연구는 솔수염하늘소의 쏠기와 탈출 행동을 유발시 키는 조건을 구명하기 위하여 구속 공간 및 온도를 달리 처리하고 탈출여부를 조사하였다. 솔수염하늘소는 직경 30 mm 이하의 공간에 구속되었 을 때 장애물을 뚫고 탈출이 가능하였다. 온도 15°C에서는 탈출에 성공하지 못하였으며, 20~30°C 범위에서 탈출 성공률이 높았다. 먹이를 이용 한 솔수염하늘소의 유인은 탈출 성공률에 영향을 미치지 않았다. 좁은 공간에 구속되지 않는 경우는 갉는 부위가 집중되지 않아 탈출공을 형성하 지 못하였다. 구속된 공간에서 솔수염하늘소는 가운데와 뒷다리 부절을 이용해 좁은 공간에서 몸을 이동시키며 큰턱으로 정면에 있는 장애물을 집중적으로 갉아서 탈출공을 만들고 앞다리를 뻗어 몸을 지탱하면서 빠져나오는 행동을 보였다. 본 연구의 결과는 훈증 대체기술로 제시되고 있 는 구속 그물망의 성능을 평가하는데 중요한 기초자료로 활용될 수 있을 것이다.
